It was carried out by employees of municipal and district State Fire Service (PSP) departments. An additional goal was to explore the relationship between the characteristics of forest areas and the responses given by respondents to the questions in the questionnaire. Introduction: It has been 20 years since the introduction of the obligation to establish fire access roads in forest areas. Fire access roads are an extremely important element of the fire protection infrastructure in forest complexes, providing the basis for planning and organising rescue and firefighting operations. Fire access roads also function as the backbone of the transport network necessary to carry out all management tasks in any forest complex. Requirements for the specifications of fire access roads are provided in general laws and, in the case of State Forests, in industry regulations. Now that twenty years that have passed since the first set of requirements for forest fire protection systems was formulated for all forests regardless of their ownership form, it seems reasonable to try to reassess their relevance. Methods: The authors analysed the data collected during a survey of employees of municipal and district State Fire Service departments from all across Poland. The survey questionnaire consisted of 10 main questions – mostly multiple-choice, with the option of adding comments. The information obtained from the surveys served as the basis for creating a database in which the responses from individual departments were grouped by province on the basis of five criteria: terrain, location on the east-west axis, forest cover, average number of fires between 2013 and 2017, and the share of private forests. The significance of the correlation between these variables was tested using the chi-square test of independence, and the correlations were checked using the Spearman’s rank correlation coefficient. Results: In the opinion of the respondents, the applicable laws in the area of forest fire protection were in most cases sufficient for the purposes of preventive operations, active protection, and rescue operations. Survey results indicate that the expected changes in regulations are related primarily to the bearing capacity of fire access road surfaces and methods of arranging fire department connections. In addition, respondents emphasised the problem of the distance between fire access roads. Respondents did not show so much agreement on the other investigated issues. But the majority of them confirmed that the applicable regulations were reasonable and needed to be strictly enforced.

It was assumed that a ventilation system should: – prevent the staircase against complete smokiness. The part of the staircase located below the level covered by the fire should be smoke-free to the extent allowing the evacuation of people from the fire compartments; – remove smoke from the staircase as fast as possible to prevent a significant increase in the level of pressure in the staircase. Project and methods: Research was conducted in a full-scale 9-storey building. Three real fires were simulated. Typical apartment furnishings were used in the fires. A smoke ventilation system was installed in the staircase with variable make-up air supply. Tests were carried out for the following configurations of smoke ventilation systems: – natural smoke exhaust with natural/gravitational make-up air; – natural smoke exhaust with a mechanical (fixed volume of 14000 m3/h) make-up air inlet; – natural smoke exhaust with a variable mechanical make-up air inlet. The position of the door between the staircase and the apartment was used as an additional variable. The measurements included temperature, light transmittance in the staircase, pressure difference between the staircase and the external environment, and the flow of the air and smoke through the smoke damper. Results: The results of the research show that the system of gravitational smoke ventilation is susceptible to ambient conditions such as temperature. In some tests, it was observed that smoke could descend below the storey covered by the fire. The conducted research helped determine the best way to reduce the amount of smoke in the staircase. The use of mechanical air supply in the smoke ventilation system facilitated fast smoke removal from the staircase, and the proper air and smoke flow direction (from the test room to smoke exhaust devices). The use of mechanical make-up air supply in the smoke ventilation system prevented the smoke from descending below the storey covered by the fire, so that the staircase on the floor covered by the fire could remain free from smoke in the lower part, providing a way of escape from the level covered by the fire. Conclusions: The conducted tests have revealed that the best solution to protect staircases without PDSs is to use a smoke ventilation system comprising a smoke vent mounted at the top and mechanically adjusted make-up air supply on the ground level.","PeriodicalId":34374,"journal":{"name":"Safety Fire Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66332151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model is based on the analogy between the theory of road traffic and the process of people’s movement during evacuation. Design and methods: In order to develop the model, a series of trial evacuations of people from public utility category ZL III buildings of varied geometry and number of users was conducted. A comparative analysis was performed concerning the evacuation times calculated with the use of models available in literature – a critical model of evacuation time, models designed by Togawa, Melenik and Booth, Galbreath, Pauls, methodology of the British Standard, and those derived from computer simulations performed with the use of the Pathfinder software. Based on the analysis of the conducted research and model considerations, an equation for the estimation of evacuation time was proposed based on a modified Greenberg’s equation derived from the road traffic theory. In the model modification, the concept of replacement length of evacuation route elements was applied, significantly slowing down people’s movement velocity, and a method for calculating them was proposed. Results: The evacuation times obtained in experimental research were compared to the model time values calculated from the models published in literature. A considerable dispersion of the achieved results was shown, ranging from –65.0% to +425.8% with respect to the evacuation times obtained experimentally. The performance of computer simulations brought evacuation times with a bias ranging from –54.4% to +26.0% with respect to the experiments conducted. Evacuation times calculated with the use of the proposed equation were in line with the experimental results with an error ranging from –12.3% to +13.8%. However, in comparison to the times obtained from additional computer simulations, representing the description of evacuation from buildings with highly varied geometry and various numbers of evacuees, the deviation of the calculated evacuation time from the proposed model was from –16.7% to +23.1%. In the vast majority of cases, the deviation of the result oscillated around ± 15% for a wide range of buildings’ geometry and the number of evacuees. Conclusions: The proposed model makes it possible to determine with sufficient accuracy the evacuation time of people from public utility buildings of category ZL III and can serve as a reliable source of comparative information.","PeriodicalId":34374,"journal":{"name":"Safety Fire Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66331704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data was obtained from cases to which Emergency Medical Services were dispatched. Most of such exposures were accidental or caused by negligence. and could be avoided by applying appropriate prevention and safety rules. Introduction: Inhalation poisonings represent a small percentage of all poisonings. They are mainly associated with the heating season and carbon monoxide. The number of inhalation poisonings is much smaller than that of food poisonings, alcohol poisonings or drug overdoses but they also constitute a significant health risk for the public. Methodology: The study was based on an analysis of medical documentation of the emergency medical services station in Łuków. The research material was composed of the information contained in the dispatch documentation of EMS teams, i.e. ambulance call records and medical rescue records for events related to inhalation poisoning. The selection of events from all those that occurred during the audited period was made on the basis of: – information provided by the reporting person to the emergency number 999 or 112, – ICD-10 code in the medical emergency record, i.e. diagnosis of the cause of the illness or event. The analysed factors included age, sex, place of intoxication, seasonality and circadian variation of poisoning. The analysis also considered environmental conditions and the influence of stimulants. Results: In the analysed period there were 80 events related to inhalation poisoning. There were 89 people exposed in 80 events (65% – men, 35% – women). Over 90% were cases of accidental poisoning. 60% of the events occurred at 7 am – 7 pm and 40% of the events occurred at 7 pm – 7 am. Of all exposures, 90% were single poisonings and the remaining 10% were multiple. Most poisonings (78%) occurred at the place of residence. Among all the victims, 56% were hospitalized in the county hospital in Łuków, 38% of patients remained at home (including due to death –20% or lack of symptoms requiring hospital treatment – 18%), and almost 6% required immediate specialist treatment. Most incidents related to inhalation poisoning in the Łuków County occurred in rural areas – 56 out of 80. Most inhalation poisonings were caused by CO.","PeriodicalId":34374,"journal":{"name":"Safety Fire Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66331559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
